About Revizo
Revizo is a spaced-repetition revision coach for DSA interview prep, living inside your LLM. Sign in once with Google, add it to any MCP client, and your editor's LLM becomes a coach that remembers every mistake you made — and resurfaces each problem exactly when forgetting starts winning.
The problem
You solved Two Sum four months ago. You failed it in one spot — a subtle off-by-one in your loop bounds. Since then you crammed fifty new problems, and nothing — not LeetCode history, not your notes app — will bring that mistake back to you.
Solving isn't revision. Interview prep culture is built around "grind 500 problems," while burn-out-by-forgetting quietly defeats most of it. Revizo exists for that gap.
The loop
No streak counters, no gamification. The loop is: attempt → honest record → resurface at the right moment. The coach sits next to your editor where you already grind — no separate app to babysit.
How scheduling works
One glance at the ladders (success intervals, in days):
| Difficulty | Success ladder (days) |
|---|---|
| easy | 1 → 3 → 7 → 14 → 30 → 60 → 120 |
| medium | 1 → 2 → 4 → 8 → 16 → 35 → 70 |
| hard | 1 → 2 → 3 → 6 → 12 → 25 → 50 |
Solved → the problem climbs one rung and comes back later. Failed → snapped back to ~1 day, mistakes recorded, and it shows up tomorrow carrying them forward. That's the whole trick.
Privacy
Every problem, attempt, and mistake is scoped to your signed-in account — nothing shared, nothing public.
